  • Why is Clean Code suggesting avoiding protected variables?

    - by Matsemann
    Clean Code suggests avoiding protected variables in the "Vertical Distance" section of the "Formatting" chapter: Concepts that are closely related should be kept vertically close to each other. Clearly this rule doesn't work for concepts that belong in separate files. But then closely related concepts should not be separated into different files unless you have a very good reason. Indeed, this is one of the reasons that protected variables should be avoided. What is the reasoning?

  • How to know whether to create a general system or to hack a solution

    - by Andy K
    I'm new to coding , learning it since last year actually. One of my worst habits is the following: Often I'm trying to create a solution that is too big , too complex and doesn't achieve what needs to be achieved, when a hacky kludge can make the fit. One last example was the following (see paste bin link below) http://pastebin.com/WzR3zsLn After explaining my issue, one nice person at stackoverflow came with this solution instead http://stackoverflow.com/questions/25304170/update-a-field-by-removing-quarter-or-removing-month When should I keep my code simple and when should I create a 'big', general solution? I feel stupid sometimes for building something so big, so awkward, just to solve a simple problem. It did not occur to me that there would be an easier solution. Any tips are welcomed. Best

  • Are too many assertions code smell?

    - by Florents
    I've really fallen in love with unit testing and TDD - I am test infected. However, unit testing is used for public methods. Sometimes though I do have to test some assumptions-assertions in private methods too, because some of them are "dangerous" and refactoring can't help further. (I know, testing frameworks allo testing private methods). So, It became a habit of mine that (almost always) the first and the last line of a private method are both assertions. I guess this couldn't be bad (right ??). However, I've noticed that I also tend to use assertions in public methods too (as in the private) just "to be sure". Could this be "testing duplication" since the public method assumpotions are tested from the unit testng framework? Could someone think of too many assertions as a code smell?

  • Database platform migration from Windows-32bit to Linux-64bit

    - by [email protected]
    We have a customer which have all they core business database on RAC over Windows OS. Last year they were affected by a virus that destroyed the registry and all their RAC environments were "OUT OF ORDER", the result, thousand people on vacation for a day.They were distrustful about Linux and after came an agreement to migrate their Enterprise Manager from Windows to Linux (OMS and Repository). How we did demonstrate how powerful and easy is RMAN to migrate databases across platforms.Fist of check of target platform is available from sourceSQL> select platform_name from v$db_transportable_platform;PLATFORM_NAME-----------------------------------------------------------Microsoft Windows IA (32-bit)Linux IA (32-bit)HP Tru64 UNIXLinux IA (64-bit)HP Open VMSMicrosoft Windows IA (64-bit)Linux 64-bit for AMDMicrosoft Windows 64-bit for AMDSolaris Operating System (x86)Check database object as directories that can change across platforms, also check external tables.Startup source database in read only modeRun the following RMAN ScriptRMAN> connect target / RMAN> convert database on target platform convert script 'c:/temp/convert_grid.rman'transport script 'c:/TEMP/transporta_grid.sql' new database 'gridbd' format 'c:/temp/gridmydb%U' db_file_name_convert 'C:\oracle\oradata\grid','/oracle/gridbd/data2/data';(Notice tha path change on db_file_name_convert)Move from source to target:PfileNew scriptsexternal table filesbfilesdata filesCheck pfile, and ensure that the paths are OKCreate temporary control file to connect rmanExecute the RMAN scriptRMAN> connect target / RMAN> @/home/oracle/pboixeda/win2lnx.rmanShutdown the instance and remove temporary control filesRecreate controlfile/s, take care about the used paths.Execute the transport script, transporta_grid.sqlDue we were moving from a 32-bit architecture to a 64-bit architecture, there is bug reported in 386990.1 note, we had to recreate OLAP , check the note for more details.

  • Ranking hit after site migration

    - by Ben
    I migrated my site from its old domain over a month ago. I followed Google Webmaster Tools completely, including 301 redirects from every existing URL to the new domain, and then submitting a change of address. Traffic continued as normal, but then a few days after submitting the change of address traffic plummeted to about 20-30% of what it was previously. Most of my traffic comes from organic search, and I can see that for the keywords I had targeted before and performed well with and am now ranking much much lower for. In some cases for low competition keywords I've only lost a few places, for higher competition terms I have really suffered. This has started to pick up a bit (one of my keywords I have risen from 195 to 100 in the last week), but it seems to be a very slow process. How seamless is this process normally? I was under the impression that this would not affect my rankings too severely, but it has now been a month since the move and recovery seems to be very slow, if at all. Is it likely that I've missed something? The only change is that I have moved what was the home page to be more of a sub-page, and now in its place is a magazine-style home page. I understand that links to the old site will now be pointing to the latter which means that rankings for some keywords attributed to the old home page will take a hit, but even on other pages that seem to fit in exactly the same page structure as the previous site I have seen a drop in rankings.

  • SQL code editor with syntax highlighing, auto-formatting and code folding

    - by Victor Stanciu
    Hello, Is there any SQL editor that supports syntax highlighting, automatic code formatting and code folding? I found this, but it's an Eclipse plugin (I'm a NetBeans user), and cannot automatically format code, which is the most important feature I'm after. Autocompletion is not important, nor is the possibility of running the code (like the SQL editor in NetBeans). Edit: I'm sorry for not specifying, I'm looking for Linux or even web-based software.

  • Code coverage (c++ code execution path)

    - by Poni
    Let's say I have this code: int function(bool b) { // execution path 1 int ret = 0; if(b) { // execution path 2 ret = 55; } else { // execution path 3 ret = 120; } return ret; } I need some sort of a mechanism to make sure that the code has gone in any possible path, i.e execution paths 1, 2 & 3 in the code above. I thought about having a global function, vector and a macro. This macro would simply call that function, passing as parameters the source file name and the line of code, and that function would mark that as "checked", by inserting to the vector the info that the macro passed. The problem is that I will not see anything about paths that did not "check". Any idea how do I do this? How to "register" a line of code at compile-time, so in run-time I can see that it didn't "check" yet? I hope I'm clear.

  • A Model for Planning Your Oracle BPM 10g Migration by Kris Nelson

    - by JuergenKress
    As the Oracle SOA Suite and BPM Suite 12c products enter beta, many of our clients are starting to discuss migrating from the Oracle 10g or prior platforms. With the BPM Suite 11g, Oracle introduced a major change in architecture with a strong focus on integration with SOA and an entirely new technology stack. In addition, there were fresh new UIs and a renewed business focus with an improved Process Composer and features like Adaptive Case Management. While very beneficial to both technology and the business, the fundamental change in architecture does pose clear migration challenges for clients who have made investments in the 10g platform. Some of the key challenges facing 10g customers include: Managing in-process instance migration and running multiple process engines Migration of User Interfaces and other code within the environment that may not be automated Growing or finding technical staff with both 10g and 12c experience Managing migration projects while continuing to move the business forward and meet day-to-day responsibilities As a former practitioner in a mixed 10g/11g shop, I wrestled with many of these challenges as we tried to plan ahead for the migration. Luckily, there is migration tooling on the way from Oracle and several approaches you can use in planning your migration efforts. In addition, you already have a defined and visible process on the current platform, which will be invaluable as you migrate.  A Migration ModelThis model presents several options across a value and investment spectrum. The goal of the AVIO Migration Model is to kick-start discussions within your company and assist in creating a plan of action to take advantage of the new platform. As with all models, this is a framework for discussion and certain processes or situations may not fit. Please contact us if you have specific questions or want to discuss migrations efforts in your situation. Read the complete article here.

  • Core Data Inferred Migration – Automatic "lightweight" vs Manual

    - by ohhorob
    I've updated the model of an existing iPhone app in some simple ways (remove attribute, add attribute, remove index), and can use automatic lightweight migration to migrate the persistent store. Due to the typical size of the data set, the processing time is not insignificant, and warrants feedback for the user. NSMigrationManager provides a simple but useful migrationProgress value that sends KVO notifications as the migration is performed. That forms the basis of providing feedback, however attempting to use an inferred model ([NSMappingModel inferredMappingModelForSourceModel:destinationModel:error:]) results in drastically different timing for the exact same dataset. Profile results on and original iPhone (2G) Automatic inferred lightweight migration PROFILE: CacheManager -migrateStore PROFILE: 0.6130 (+0.6130) models loaded PROFILE: 1.1759 (+0.5629) delegate -CacheManagerWillMigrate: PROFILE: 1.2516 (+0.0757) persistent store coordinator loaded PROFILE: 5.1436 (+3.8920) automatic lightweight migration completed PROFILE: 5.5435 (+0.3999) delegate -CacheManagerDidFinishMigration:withError: Manual inferred migration PROFILE: CacheManager -migrateStore PROFILE: 0.6660 (+0.6660) models loaded PROFILE: 1.1471 (+0.4811) inferred mapping model generated PROFILE: 1.4046 (+0.2574) delegate -CacheManagerWillMigrate: PROFILE: 1.5058 (+0.1013) persistent store coordinator loaded PROFILE: 22.6952 (+21.1894) manual migration completed PROFILE: 23.1478 (+0.4525) delegate -CacheManagerDidFinishMigration:withError: So, with an inferred model, the manual migration takes over 5 times longer than automatic! It's a big inconsistency, and the lightweight option that NSPersistentStoreCoordinator -addPersistentStoreWithType:configuration:URL:options:error: provides absolutely no indication of progress while processing. Can anybody provide a supported way to get the migrationProgress values during automatic migration, OR a way to configure an inferred mapping model to be as fast during manual processing as automatic?

  • Windows Server 2012 Migration (DNS/AD DS Standard Eval to Essentials OEM) P2V -> Do I need a Secondary Domain Controller during migration?

    - by Aubrey Robertson
    This is my first post on this exchange (although not my first on stack exchange), so please have patience. I am a 3rd year student intern, and I have been tasked with virtualizing the server systems at the company I work for. I have come a long way, and I am almost ready to install the VM Server in migration mode. Here is some information: Source Server: Windows Server 2012 Standard Evaluation DNS Server (local only) Advanced Directory Domain Services File and Storage stuff A few other server roles Destination Server: Windows Server 2012 Essentials OEM (Hyper-V client) Running under a temporary Hyper-V host (will migrate the Hyper-V host back to the old machine after the original server is virtualized as a client). Sitting currently at the "Select Installation Mode" screen. I have been following the guides on Microsoft tech net, and today I spent most of the day getting rid of issues in the Best Practices Analyser on the source machine. I have 3 remaining issues (which are all related): ERROR: DNS: DNS servers on Ethernet (adapter name) should include the loopback address, but not as the first entry (flavour text indicates that, during migration, the DNS server may not be found) WARNING: All domains should have at least two domain controllers for redundancy. WARNING: DNS: Ethernet should be configured to use both a preferred and an alternate DNS Server. All of these issues can be resolved by deploying a secondary domain controller, but I have never done that before (see my concerns below). The main issue here that I am concerned with for installing in migration mode is the FIRST one (the error). If I try and set-up the new server deployment, and the adapter domain controller is listed as localhost, then this may cause the installation to fail. (at least, this is what the Microsoft documentation suggests). But I do not have another IP address to enter here as I have no other local domain controllers. So I did the first obvious thing that came to my mind, and tried to use Google DNS servers as my alternates. That did not work because they couldn't recognize other computers in the "forest". Now I'm no expert when it comes to DNS, so please forgive my ignorance. This DNS server is concerned only with Active Directory stuffs for the local network. If I go ahead with migration, and it fails, then I will just have to go ahead and install a secondary DNS server I suppose. The problem I have here is that I am limited by the amount of Windows Server keys I have available (I have 2); however, I do have access to a Linux box running Debian Wheezy that I set-up two weeks ago as a Mantis server. I could install Windows Server 2012 as a secondary DNS (I think) in a VM and use that, but then it seems like I will be wasting time, and probably the Windows key too, and if there's another way to do it with Linux that would be much better. Even better still, do I even need a secondary DNS server for migration at all? The hints said that during migration the original machine "might" not be found. Thank you for your time and consideration.

Out of the box, Soapi provides you with a robust client library that abstracts away most all of the messy details of consuming the API and lets you concentrate on implementing your ideas. A few features include: A fully relational model of the API data set exposed via a fully 'dot navigable' IEnumerable (LINQ) implementation. Simply tell Soapi what you want and it will get it for you. e.g. "On my first question, from the author of the first comment, get the first page of comments by that person on any post" my.Questions.First().Comments.First().Owner.Comments.ToList(); (yes this is a real expression that returns the data as expressed!) Full coverage of the API, all routes and all parameters with an intuitive syntax. Strongly typed Domain Data Objects for all API data structures. Eager and Lazy Loading of 'stub' objects. Eager\Lazy loading may be disabled. When finer grained control of requests is desired, the core RouteMap objects may be leveraged to request data from any of the API paths using all available parameters as documented on the help pages. A rich Asynchronous implementation. A configurable request cache to reduce unnecessary network traffic and to simplify your usage logic. There is no need to go out of your way to be frugal. You may set a distinct cache duration for any particular route. A configurable request throttle to ensure compliance with the api terms of usage and to simplify your code in that you do not have to worry about and respond to 50X errors. The RequestCache and Throttled Queue are thread-safe, so can make as many requests as you like from as many threads as you like as fast as you like and not worry about abusing the api or having to write reams of management/compensation code. Configurable retry threshold that will, by default, make up to 3 attempts to retrieve a request before failing. Every request made by Soapi is properly formed and directed so most any http error will be the result of a timeout or other network infrastructure. A retry buffer provides a level of fault tolerance that you can rely on. An almost identical javascript library, Soapi.JS, and it's full figured big brother, Soapi.JS2, that will enable you to leverage your server cycles and bandwidth for only those tasks that require it and offload things like status updates to the client's browser.

  • Clean Code: A Handbook of Agile Software Craftsmanship – book review

    - by DigiMortal
       Writing code that is easy read and test is not something that is easy to achieve. Unfortunately there are still way too much programming students who write awful spaghetti after graduating. But there is one really good book that helps you raise your code to new level – your code will be also communication tool for you and your fellow programmers. “Clean Code: A Handbook of Agile Software Craftsmanship” by Robert C. Martin is excellent book that helps you start writing the easily readable code. Of course, you are the one who has to learn and practice but using this book you have very good guide that keeps you going to right direction. You can start writing better code while you read this book and you can do it right in your current projects – you don’t have to create new guestbook or some other simple application to start practicing. Take the project you are working on and start making it better! My special thanks to Robert C. Martin I want to say my special thanks to Robert C. Martin for this book. There are many books that teach you different stuff and usually you have markable learning curve to go before you start getting results. There are many books that show you the direction to go and then leave you alone figuring out how to achieve all that stuff you just read about. Clean Code gives you a lot more – the mental tools to use so you can go your way to clean code being sure you will be soon there. I am reading books as much as I have time for it. Clean Code is top-level book for developers who have to write working code. Before anything else take Clean Code and read it. You will never regret your decision. I promise. Fragment of editorial review “Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way. What kind of work will you be doing? You’ll be reading code—lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft. Readers will come away from this book understanding How to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.” Table of contents Clean code Meaningful names Functions Comments Formatting Objects and data structures Error handling Boundaries Unit tests Classes Systems Emergence Concurrency Successive refinement JUnit internals Refactoring SerialDate Smells and heuristics A Concurrency II org.jfree.date.SerialDate Cross references of heuristics Epilogue Index

  • code first CTP5 error message

    - by user482833
    I get the following error message with a new project I have set using code first CTP5. Can't find anything on the web about it. Has anyone encountered this error message? The context cannot be used while the model is being created. This occurs the first time my database context is called (code below): using (StaffData context = new StaffData()) { return context.Employees.Count(e = e.EmployeeReference) == 1; } At this point the database has not been created. I have a database initialiser DropCreateDatabaseIfModelChanges which I set in app_start.

  • Code Formatter: cleaning up horribly formatted jsp code

    - by ahiru
    So I am working on a jsp/servlet that came to me and I'm looking at the jsp file and it is just a jungle of jstl tags, java code and html thrown together. At first it looked like someone ran the standard eclipse formatter on it and had the page width set to 40 so alot of stuff is broken up, I tried to format it with a larger page width but that seemed to make it worse to the point of not being able to tell what is going on without formatting parts of it first. Anyone have any luck with any jsp/code formatter?

  • Best way to relate code smells to a non technical audience?

    - by Ed Guiness
    I have been asked to present examples of code issues that were found during a code review. My audience is mostly non-technical and I want to try to express the issues in such a way that I convey the importance of "good code" versus "bad code". But as I review my presentation it seems to me I've glossed over the reasons why it is important to write good code. I've mentioned a number of reasons including ease of maintenance, increased likelihood of bugs, but with my "non tech" hat on they seem unconvincing. What is your advice for helping a non-technical audience relate to the importance of good code?

  • What's the most effective way to perform code reviews?

    - by Paddyslacker
    I've never found the ideal way to perform code reviews and yet often my customers require them. Each customer seems to do them in a different way and I've never felt satisfied in any of them. What has been the most effective way for you to perform code reviews? For example: Is one person regarded as the gatekeeper for quality and reviews the code, or do the team own the standard? Do you do review code as a team exercise using a projector? Is it done in person, via email or using a tool? Do you eschew reviews and use things like pair programming and collective code ownership to ensure code quality?

  • Shouldn't all source code be plain text? [on hold]

    - by user61852
    Some developing environment/languages save the source code you write in a binary/propietary format that you cannot see or edit with a generic text editor. I'm not talking about compiled code, but the source code. An example could be PowerBuilder and Oracle Forms. It's ok you use proprietary technology if you want, but not being able to open the source code you wrote, in a simple editor, if only to read it, seems like a very strict form of vendor lock-in. Also this prevents you from using text-based version controls that can show you the difference between two versions in a line-by-line base. If the code is plain text, you don't need a license in order to just open it, see it and learn from it. Should it be a golden rule to avoid vendor lock-in to avoid technologies that save your source code to anything but plain text files ?

  • Writing a Javascript library that is code-completion and code-inspection friendly

    - by Vivin Paliath
    I recently made my own Javascript library and I initially used the following pattern: var myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); The problem with this is that I can't really use code completion because the IDE doesn't know about the properties that the function literal is returning (I'm using IntelliJ IDEA 9 by the way). I've looked at jQuery code and tried to do this: (function(window, undefined) { var myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); window.myLibrary = myLibrary; }(window)); I tried this, but now I have a different problem. The IDE doesn't really pick up on myLibrary either. The way I'm solving the problem now is this way: var myLibrary = { func: function() { }, func2: function() { }, prop: "" }; myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); But that seems kinda clunky, and I can't exactly figure out how jQuery is doing it. Another question I have is how to handle functions with arbitrary numbers of parameters. For example, jQuery.bind can take 2 or 3 parameters, and the IDE doesn't seem to complain. I tried to do the same thing with my library, where a function could take 0 arguments or 1 argument. However, the IDE complains and warns that the correct number of parameters aren't being sent in. How do I handle this?
